Sampling Cell for DMT348
It may be necessary to use a sampling cell if the process (for example a
pipe) is too small for the DMT348 probe. Furthermore, if the process is
very hot (>80 °C) or particularly dirty, the probe is installed in a
sampling cell behind a cooling coil and/or filter. In this case, the ambient
temperature must be at least 10 °C warmer than the process dewpoint in
order to avoid condensation in the sample tubing.
Sampling Cell with Swagelok Connectors (Vaisala order code:
DMT242SC2) and Sampling Cell with Female Connectors (Vaisala order
code: DMT242SC) are available as an option.
